ABSTRACT Previous researches have established that the swim speed of some microcrustaceans is influenced by chemical compounds emitted by conspecifics. We examined the hypothesis that cuticular compounds present on the body surface of A. franciscana, the most widespread member of Artemia genus, play a role in the swim speed of conspecific males. The movements (swim) of one male confronted to a sponge soaked with female or male cuticular extract, were recorded during 30 minutes and the swim speed was determined using a behavioral tracking software (Ethovision 3.1, Noldus Technologies). As a control, the movements of one male confronted to a sponge soaked with salty water or with a mixture of the solvents used in the extraction (chloroform-methanol), was... |

Trials on the seabass weaning in atlantic marshes (Roux, 1993), have shown that the use of frozen prey improved this step and reduced his resulting stress. During the present study, which must confirmed these preliminary results, three alimentary sequences were tested. 1) natural zooplankton, weaning pellets, as control, 2) natural zooplankton, inert artemia (intensively produced), weaning pellets, 3) natural zooplankton, natural frozen zooplankton (harvested), weaning pellets. The achieved results show that weaning with intermediary phases (sequences 2 or 3) yield best results. Furthermore the phase with artemia yields, systematically, better results than with harvested zooplankton ; then artemia seems a excellent substitute food representing a... |

Heat shocks at 40 degree were delivered to Artemia at the end of embryonic development and at the beginning of postembryonic development and their effects on subsequent development examined. Heat shocks delivered during preemergence development have no effect on subsequent development. Heat shocks delivered to newly hatched nauplii induce anomalies on the morphogenesis of thoracic and genital appendages. The induction of morphological anomalies by thermal conditions prevailing during early larval life makes it easier to integrate the morphological effects previously induced by nutritional conditions imposed to older feeding stages. |

Lactic acid bacteria (LAB) were isolated from rotifer cultures in a marine hatchery to search for potential probiotics for marine animals. Fifteen strains were first selected among a total of 55, according to antibacterial activity against Vibrio sp. Among eight strains identified as Lactobacillus casei, four were highly adhesive, suggesting some ability for surface colonization. The other strains were identified as Lactobacillus plantarum, Lactobacillus dextrinicus, and Leuconostoc sp. To validate probiotic potential, Artemia were challenged against pathogenic Vibrio alginolyticus, with or without one of six selected LAB strains. The six strains protected Artemia against the pathogen, to some extent on condition that nutrient enrichment was provided. La.... |

Formaldehyde was used to disinfect Artemia cysts and nauplii, while introducing two probiotics in the enrichment process: Bactocell (Pediococcus acidilactici) and Levucell (Saccharomyces cerevisiae). The disinfectant was selected due to its potential compatibility with probiotics, since it was more effective against Gram-negative bacteria than against lactic acid bacteria and yeast. However, the presence of formaldehyde reduced the intake of P. acidilactici in Artemia. Consequently, the disinfection was stopped before Bactocell supplementation to the nauplii fed to pollack (Pollachius pollachius) larvae. The mean weight of pollack was higher with this probiotic treatment. Growth was even better with the combination of Levucell and Bactocell, but the yeast... |

Until recently, it was considered impossible to feed newly hatched marine fish species with a compound diet. Substituting a compound diet for live prey was performed several weeks after hatching, depending on the species. Compound diets were well ingested at the early stage but larvae died with a gut full of food, suggesting that larvae were unable to digest the compound diet. The hypothesis was that younger larvae have insufficient digestive enzymes to thrive on compound diets, and that exogenous enzymes, provided from live prey, are necessary for early stages. The organogenesis of marine fish larvae is not completely achieved at hatching and histological studies have revealed that the anatomy of the digestive tract undergoes developmental changes over... |

RESUME La saline de Sfax constitue un site potentiel pour l’exploitation et la production de l’Artemia locale. Des quantités importantes d’Artemia sont exploitées chaque année (60 kg de cystes poids sec) et sont utilisées en alimentation larvaire. Afin de démontrer l’impact de divers rejets industriels, agricoles dans cette saline, nous avons procédé à la détermination de quelques métaux traces toxiques : le mercure (Hg), le cadmium (Cd), le plomb (Pb), le cuivre (Cu) et le zinc (Zn) par une analyse en spectrophotométrie d’absorption atomique, ce qui nous permettra d’évaluer le degré de contamination par ces métaux dans les cystes et la biomasse d’Artemia. Les résultats obtenus ont montré que les concentrations aussi bien au niveau des cystes que de la... |

Le branchiopode Artemia représente le principal organisme vivant colonisant les biotopes hypersalés. L’étude taxonomique de l’Artemia au niveau de la région ouest méditerranéenne, incluant l’Italie, la France, l’Espagne, le Portugal et le Maroc, a révélé la présence de l’espèce Artemia franciscana (qui a pour origine le continent Américain) comme étant une espèce invasive. Dans ce travail, une nouvelle population d’Artemia a été rapportée pour la première fois au niveau de Sabkhet Halk El Manzel. Une première identification taxonomique de cette population a été réalisée moyennant une étude morphologique et comparative de la forme de l’ovisac des femelles avec cinq autres populations tunisiennes appartenant à l’espèce Artemia salina et avec l’espèce... |

Due to commercial availability of dried cysts from which live test material can be hatched at will, <i>Artemia</i> is used extensively in research and applied toxicology.Despite the extensive literature on dose-effect relationships of chemicals on brine shrimp, it was not until 1980 that an experimental protocol was developed for a simple acute toxicity test with <i>Artemia</i> nauplii, meeting the prerequisites for standardization.The reliability and accuracy of this short-term test were determined during an intercalibration exercise involving 80 laboratories and were found to be quite satisfactory. Consequently, the so-called ARC-test, which is one of the very few standardized marine toxicity tests, is now used routinely at the... |

Variations in dry weight, caloric content and ash content during cyst hatching and early larval development have been studied for various geographical strains of <i>Artemia</i> . In general, decapsulated cysts contain 30 to 40% more energy than freshly hatched nauplii; for Chaplin Lake and Buenos Aires <i>Artemia</i> this difference amounts to 57%. Ash contents increase as decapsulated cysts hatch into instar I and molt into instar II-III nauplii. Over a 24h larval developmental period individual dry weights and energy content of the nauplii decrease with 16-34% and 22-37% respectively.A small but significant correlation exists between the survival rate of starved nauplii and either the energy content of instar I and instar II-III... |

As described in our previous paper (Sorgeloos et al. , 1977) hypochlorite can be used as reactive agent to dissolve the lipoproteic chorion of <i>Artemia</i> cysts. Two commercial products are available worldwide, i.e. bleaching powder, chloride of lime Ca(OCL)<sub>2</sub> and bleaching water NaOCl solutions. In Western Europe the latter product is the cheapest, whereas in the USA and Southeast Asia bleaching powder should be considered. Because the decapsulation process is a much more critical operation with bleaching powder, especially with regard to the viability of the embryos (Bruggeman et al., in preparation; Manzi, personal communication), we studied the use of technical NaOCl solutions in detail. |

<i>Artemia</i> juveniles were cultured under intensive conditions in three series of six tanks at different times. Both plate counts and Biolog GN microtitre plates were used to monitor the microbial community. Repetitions of the <i>Artemia</i> cultures in time revealed significant differences in Biolog patterns and bacterial counts, showing that normal culture practices, including chlorination of the sea water, does not allow control of the associated microbial community. However, the similarity among the Biolog fingerprints of all 18 tanks as determined by the Pearson correlation coefficient was always high. Both observations together indicate that the microbial community which colonizes the culture tanks seems to be determined by... |

The recent developments in aquaculture production of fish and shrimp have resulted in increased demands for <i>Artemia</i> cysts and biomass as valuable sources of life food. Solar salt works are suitable biotopes for the integrated exploitation of salt, <i>Artemia</i> and eventually fish or shrimp. <i>Artemia</i> may be present as a natural resource in local saltworks; however in some situations characteristics of the endemic strain might justify the introduction of another <i>Artemia</i> species to increase productivity. |
